• Java, Linux : 2nd call to ffmpeg via Runtime not getting executed

  21 février 2018, par We are Borg

  I am trying to convert video to gif. I am using ffmpeg and imagemagick to achieve this. The first step is successful where a mp4 is created, but the 2nd process is not getting called. If I run the command manually, then it all works fine, but not via code. What am I doing wrong ? Thank you.

  Error log :

  2nd phase code never gets executed...the Runtime process. What am I doing wrong ? Thank you.

• Image files as inputs with AWS Elastic Transcoder ?

  7 décembre 2017, par Geuis

  Here’s my situation. I’ve been working on building a service at work that takes dynamically generated images and outputs animations as mp4 or gif. The user has the options of setting dimensions, time for each frame, etc.

  I have this working currently with ffmpeg. It works ok, but is difficult (and potentially expensive) to scale due largely to the cpu/memory requirements that ffmpeg needs.

  I just spent some time experimenting with AWS’s Elastic Transcoder. It doesn’t seem to like static image files (jpg, png) as source material in jobs. The file types aren’t listed under the available Preset options either.

  I’m sure that I could adapt the existing architecture to save the static images as video files (sound isn’t needed) and upload those. That will still require ffmpeg to be in the pipeline though.

  Are there any other AWS services that might work with my needs and allow the use of Elastic Transcoder ?
